Where to get a neodymium magnet?
Neodymium magnets are known for their unique strength. Due to the perfect alloy of iron, boron and rare earth metal neodymium, they have the strongest magnetic properties among the permanent magnets known to mankind. The scope of their application is quite wide, but nevertheless, to buy such a magnet is sometimes very difficult or expensive. Our article aims to tell where to get a neodymium magnet, this is the eighth wonder of the world.
These magnets are the source of the strongest magnetic fields. Accordingly, it is necessary to look for them where you need the maximum power of magnetism with minimum energy expenditure. After all, electromagnets have huge energy losses, which often makes their use unprofitable. Or, in view of the design features, electromagnets cannot be used at all.
It all depends on what size you need a magnet. The largest neodymium magnets are production ones, but it is almost impossible to get them. In everyday life, these super-powerful magnets can be found in acoustic systems.Better in the old, Soviet: in those days did not stint on the glands.
Where can I get a small neodymium magnet? Of course, our friend is a computer. In a hard disk drive (HDD), neodymium magnets are always used in the positioning device. It is better to look for hard drives "older" - up to 1 GB. Our contemporaries once again distinguished themselves by their economics and in HDD they use quite flawed neodymium plates.
